…ope verify to declared schema * introspect: when the live DB has no FK constraints, infer relations by matching a column's name and pg_type to another table's PK. Inferred references are tagged so the renderer marks them with "inferred from naming convention; verify" for human review. Resolves .include() silently failing on schemas created without explicit REFERENCES clauses. * render: keep .primaryKey() on columns that are both PK and FK (e.g. 1:1 mapping tables like ai_summaries(case_id)). The FK branch was emitting fk(...).notNull() and dropping the PK marker. * verify: read $schemaName from the loaded defineSchema(...) and pass it to introspect, so drift only scans the Postgres schema this app owns. Eliminates false drift from sibling apps' tables in the same Lakebase database.

Brownfield support for existing Lakebase/Postgres schemas. This layer lets AppKit inspect a live database, render schema files, detect drift, and manage migrations from the CLI.
Introspection + rendering
Adds the introspector engine, Drizzle adapter, schema-to-introspection bridge, SQL rendering, type mapping, and roundtrip tests.
Drift detection
Adds boot-time drift detection with fatal/warn classifications, production fail-closed behavior for unsafe drift, live-only warnings, healthz saturation, and pg-to-http error mapping.
Database CLI
Adds
appkit db introspect,generate,migrate,verify,setup:dev,seed, and migration helpers.Test plan
